1.1 1. The tables on the following pages have been prepared by the Estonian Tartu Observatory and are reproduced here with their permission. The tables include 8 public aerodromes.

1.1 The times in the tables are given in UTC for beginning of civil morning twilight (TWIL FROM), sunrise (SR), sunset (SS), and end of civil evening twilight (TWIL TO) for the years from 2010 to 2020.

1.2 The times given for the beginning of civil morning twilight and end of civil evening twilight are calculated for an altitude of the Sun 6° below the horizon, as commonly used.

1.3 The tables are calculated for the year 2014, which is used as an “average year” for the years from 2010 to 2020. In this period, the times on an arbitrary date and place will deviate less than 2 minutes from the times on the same date and place in the “average year”.
